> people install adblockers typically because they find the ads are intrusive (full-screen graphic overlays, etc), or their machine gets infected with ad network-delivered malware. If you presented ads that were respectful to the visitor (i.e. weren't offensive) I expect the blocker escalation war would cease.

This is absolutely incorrect. Users may install them because they find some amount of ads to be abusive, but damn near nobody (relative to all ad blocker usage) starts out on a white list basis, and the idea that they're diligent about unblocking sites that have "good" ads that get past their blocker is just absurd.
